Sometimes it is still hard to believe that love, hope, joy, and goodness still exist in the world after we experienced the loss of a loved one. And that it is ok. It is ok to doubt-chances are that this death has caused us to question many things including who are we?, what does the future look like?, and can we every be happy again? These are legitimate questions to ask and we don't have to let anyone convince us otherwise. Did you know most existential philosophers experienced the death of a loved one early on in their lives? They asked the hard questions that seemingly don't have any answers.
However, we just might need to be careful who we ask those questions in front of. Not everyone can handle it. About 1/3 of the people in our lives won't be able to sit with us in our grief and will actually respond negatively to us. Another third won't have the time or the emotional capacity but won't intentionally hurt us. Maybe 1/3 or less will actually understand or try to understand what we are going through and will sit with us in the silence, the tears, and the questions. They won't try to make us feel better, they won't try to answer the questions. They will simply hold the space for us to ask and that is probably the greatest gift anyone can give to someone who is grieving.
